[Introduction]：Le NB144ES-V2 est le serveur de port série 4 canaux de deuxième génération d'Ebyte. Il intègre une pile de protocoles TCP/IP et permet la transmission de données série vers Ethernet bidirectionnelle transparente, la conversion de protocole Modbus et la connectivité cloud des périphériques série. Prenant en charge la configuration des ordinateurs hôtes, il est largement utilisé dans des secteurs tels que la surveillance des salles informatiques et la surveillance environnementale. Il est doté d'un revêtement conforme pour une résistance à la moisissure, à l'humidité et au brouillard salin.
